FIELD

Embodiments of the invention relate to a commercial modem/router and a wireless system of data communications. The method and system generally uses two radio transceivers for an inexpensive data and communication device usable without the need for construction or hardwiring.

BACKGROUND

Hybrid fiber coaxial networks (HFC networks) are typically used for delivery of television signals to subscribers. Each subscriber represents either an individual or a business and is connected to the cable TV HFC network through a trunk and branch configuration to individual subscribers.

The HFC network can also carry a connection to the Internet, voice, fax and data. To date, customers in business have had great challenges in connecting to the HFC network. The present invention was designed to meet that need.

A need has long existed to expand the serviceable market to provide Internet, voice, fax, and data connectivity. The present invention addresses the need to a less expensive and faster technique to permit customers to access these services over cable in commercial facilities.

Another need in the business was to have a system that can be used through a window so that no roof rights are required by a client for connecting to the HFC network.

The wireless communication device can comprise a housing containing a bidirectional high speed data modem operably connected to a first radio transceiver, a first radio processor card, and a switching power supply. The device can further have a splitter adapted to engage the coaxial cable and split the RF spectrum signal from the AC power. The device can also have at least one heating and cooling device adapted to heat and cool contents of the housing.

Returning to FIG. 1, a cable modern/router (12), such as a DOCSIS cable modern/router, is disposed in a housing (13). The cable modern/router and housing are connected to a supporting strand (18), such as with a first mounting bracket (10) and a second mounting bracket (11). The supporting strand supports a fiber/coaxial cable (19). The housing is preferably water or weather resistant housing, such as one made from molded plastic, metal, a composite, a weatherproof water tight coated laminate or combinations thereof. The housing is large enough to hold the cable modem/router, at least one heating and/or cooling device, one or more radio transceivers, a power supply converter, thermostat (107), and associated cables. The housing can also include a lightning protector.

The supporting strand (18) described in the invention is shown in detail in FIG. 2, wherein the strand supports the fiber/coaxial cable (19) which contains an RF spectrum signal (20), which is preferably a CATV signal, but can also be other types of signals. The RF spectrum signal can have digital content, such as digital music, and also return information, such as compressed video libraries. The coaxial cable (19) also provides a source of AC power (22) which is typically between approximately 50 volts up to and slightly exceeding 100 volts. In one embodiment, the supporting strand (18) and the fiber/coaxial cable (19) are sealed inside a material, such as rubber.

The power results from the AC power being split from the coaxial cable then can be transmitted to a switching power supply such as a switching power supply from Integrated Power Design, which can convert and regulate the AC to DC power. The outputs are between about 0.1 volts to about 48 volts of DC current. One or more outputs of the switching power supply can have this voltage. In the embodiments, the outputs are between about 9 volts to about 12 volts each. The first processor card (105) can communicate with a radio transceiver (15).

The first radio transceiver (15) can further communicate with a first antenna (101) via an RF cable (102). Antennas manufactured by Arc Wireless of Denver, Colo. can be used in the invention, but additional antennas can also be used.

The method can generally includes splitting (302) the signal with an RF/power splitter from the coaxial cable into the RF spectrum signal and the AC power.

The method can further include transmitting (304) the RF spectrum signal from the splitter into the bidirectional high speed data cable modem/router and generating a digital Ethernet signal (306) from the modem/router to the first processor card and the first radio transceiver.

In addition, the method can include converting (308) the AC power to DC power using a converter and stepping down the voltage with a switching power supply. The switching power can then be used to supply power to the modem/router, processor and the radio transceiver, as well as a plurality of heating and cooling devices (310). The heating and cooling devices can be adapted to heat or cool the contents of the housing.

Continuing with FIG. 3, the processor signals are communicated from the processor PCB to the first radio transceiver (312).
